The question there is whether they attempt to correctly simulate all the systems of anything or not? I’ve never seen a claim from Carenado to have “accurate” systems, just “custom” ones.

I’ll stand corrected if someone can show me otherwise, but personally I’ve never actually expected accurate systems from Carenado. Heck, altitude hold on the autopilot is a minor miracle from their avionics.

As Ian says, `old` data is based on what is present in the sim. I find it fatuous to argue with buffoons who think that upgrading the database puts them into todays’ environment. It doesn’t.

As for Carenado they are now modelling more system-complex aircraft when they didn’t even correctly model the systems of the simple.
While their external modelling is easily among the best, ther flight modelling is improving and now among the better, this still leaves them as the worst of the sophisticated sim developers, with the exception of Iris.
Reach exceeding grasp..?
